Loading Media into the Printer 

In addition to loading roll media in the printer, you can: 

• Use the peel-off option. 

• Load fanfold media. 

You can load media with the printer power turned on or off. The 
following procedures for loading media assume that you have 
turned on the printer. Refer to the EasyCoder 7421 Printer Setup 
Guide for instructions on loading rolls of media. 

Using the Peel-Off Option 

Use the peel-off option in printing applications where you want 
to apply labels to a surface immediately. After printing a label, 
the printer presents the label with the backing removed. 

Note: You should find a small label with a three-digit sensitivity 
number printed on it attached to your roll of media or a 15-digit 
number stamped on the side of the media roll. Save this information. 
You will need it to set the correct media sensitivity number. For help, 
see "Setting the Media Sensitivity Number" in Chapter 2. 

Note: Intermec does not recommend using fanfold media with the 
peel-off option.

Configuring the Printer 



Use this chapter to learn how to configure your 7421 printer, 
communicate with a PC, and print a test label with PrintSet. 

Configuring the Printer 

You are now ready to configure the printer by downloading data 
from the host to the printer. For your printer to operate most 
effectively, you need to configure: 

• the media sensitivity number 

• the print darkness 

• the label gap sensors 

Setting the Media Sensitivity Number 

Media sensitivity is important because you use it to optimize 
print quality. The three digit media sensitivity number (MSN) 
specifies the amount of heat required by the printhead to image a 
label. The amount of heat that each roll of media or ribbon 
requires is unique due to different chemistries and 
manufacturing processes. 

Intermec has developed heating schedules (the amount of heat 
required to image a label) to produce the highest possible print 
quality for Intermec media and ribbon combinations on Intermec 
printers. Look for the three digit media sensitivity number on: 

• the side of the media roll. Use the last three digits (140 in the 
example) of the 15 digit number stamped on the roll for the 
media sensitivity number. 

• a small label attached to the roll of media. 

• a small label attached to the plastic bag of your ribbon roll. 
Your label may be different from this example, but it will 
contain the media sensitivity number. 



2-3 



Finding Your Media Sensitivity Number 




Note: Some ribbon rolls have the media sensitivity number printed on 
the inside core. 

Use this three-digit number to optimize print quality and print 
speed on your printer. You can achieve the best print quality on 
the printer by using only Intermec ribbon and media products. 
The default sensitivity setting for thermal transfer media is 567. 
For direct thermal media, the default sensitivity setting is 180. 

To change the media sensitivity number with PrintSet 

1. Start the PrintSet application software. 

2. Click the Paper type button. 



3. In the Print Quality Setup dialog box, enter your three-digit 
number in the Media Sensitivity Number field. 

4. Click OK. 

5. Download your change to the printer by pressing the button 
to send command updates to the attached printer. 



w\ 



2-4 



Setting the MSN for Intermec Media and Ribbon 

For direct thermal media, use the three-digit media sensitivity 
number located on the roll of media to set the media sensitivity 
number. You can also use the values from the tables in the next 
section. 

For thermal transfer media, you need to look in two places to 
determine the sensitivity number. The media sensitivity number 
on each roll of thermal transfer media or ribbon has an asterisk 
(*) in place of one of the digits. On thermal transfer media, the 
number contains the first and second digits, with an asterisk in 
place of the third digit. One the thermal transfer ribbon, the 
number contains the first and third digits, with an asterisk in 
place of the second digit. 

To optimize the sensitivity number for thermal transfer media, 
you combine the digits like this: 



Media or Ribbon 

Thermal transfer 
media 



Thermal transfer 
ribbon 



Sensitivity Number 

56* 



5*7 



567 



Description 

The asterisk reserves the 
third digit to identify the 
ribbon's sensitivity 
number. 

The asterisk reserves the 
second digit to identify 
the media's sensitivity 
number. 



Optimal media 
sensitivity number 



2-5 



Setting the MSN for Other Media and Ribbon 

If you are not using Intermec media and ribbon, or if you 
misplaced your packaging with the three digit-sensitivity 
number label on it, you can set an approximate sensitivity 
number. The first column of the Direct Thermal and Thermal 
Transfer Media Sensitivity Settings tables list the approximate 
sensitivity settings. To achieve acceptable print quality, enter the 
three-digit media sensitivity number (for example, 600). 

If you are unsure of how to set the media sensitivity number, 
start with the highest setting, which provides the lowest energy 
(600 for thermal transfer and 400 for direct thermal), and work 
your way down until you achieve the best print quality.

Adjusting the Print Darkness 

Use the print darkness adjust to fine-tune the darkness of print 
on your labels. The fine adjustments compensate for variations in 
the media ("lot to lot"), the printhead, or the printer. The 
darkness adjustment is similar to the dark adjust available on a 
copier. An increase in print darkness increases the energy to the 
printhead and results in darker print. A decrease in print 
darkness decreases the energy to the printhead and results in 
lighter print. 

Set the darkness after you enter the media sensitivity number. 
You can adjust the print darkness from + 10 to -10. 

To adjust the print darkness with PrintSet 

1. Start the PrintSet application software. 

2. Click the Paper type button. 



3. In the Print Quality Setup dialog box, adjust the Print 
Darkness slider bar until the setting that you want appears 
underneath it. 

4. Click OK. 

5. Download your change to the printer by pressing the button 
to send command updates to the attached printer. 



w\ 



2-8 



Adjusting the Label Gap Sensor 

The label gap sensor detects the gap between labels while they 
are being printed. The gap sensor automatically calibrates itself 
when you first turn on power to the printer. This adjustment 
compensates for manufacturing differences in label stock that 
may make it difficult for the gap sensor to detect the gap 
between labels. 



To adjust the label gap sensor 

1. Turn the printer power off. 

2. Turn the printer power on. 

The printer Power light flashes yellow and the printer advances 
to the next label. When the label gap sensor adjustment is 
complete, the Power light stops flashing and turns green. 



2-9 



Communicating With the Printer 

Downloading is the universal term used to describe the transfer of 
information from the host to any connected peripheral device, 
such as your printer. When you transfer data from your printer 
to the PC or host, you are performing a process called uploading. 

You can use several methods to download information to your 
printer. Use these products to communicate with your printer: 

PrintSet Application Software Use the PrintSet application 
software to easily configure your printer from your PC. You can 
upload the current configuration settings, modify them, and then 
download them to your printer. PrintSet also lets you: 

• download graphics and fonts. 

• print test labels using resident fonts, user-defined bitmap 
graphics, or resident bar code symbologies. 

• allocate printer memory. 

• download configuration files to multiple printers. 

For help using PrintSet, refer to the online help portion of the 
application software. 

Intermec Printer Language (IPL) Commands You can create labels 

by downloading formats (designs) and data with IPL commands. 
You can use the printer IPL commands to perform functions and 
activate features of the printer. See the IPL Programming Reference 
Manual for more information. 

Third-Party Software You can use third-party software to set 
many of the printer parameters. You can use PrintSet or the IPL 
command set to configure the parameters that your software 
does not set. 

Use your third-party software to create label formats and convert 
graphics into a user-defined character (UDC) format that the 
printer can interpret. 

Printing a Test Label 

If you would like to test your communications by downloading a 
label, follow the example below. Use the PrintSet application 
software to send a test label to the printer. 

2-10 



To print the test label 

1. Start the PrintSet application software. 

2. Click the Test Print button: 



G 



3. Select the Test Label option button. 

4. Select either the Text or the Bar Code option button. 

If you select text, you can choose any font in the Select Printer 
Font list box. 

If you select bar code, you can choose any symbology in the 
Select Symbology list box. 

5. Click the Print button. Your 7421 printer prints out a test 
label. 



2-11 



For example, if you choose to print a bar code with the Code 
39 symbology, your printer prints out a label similar to this 
one: 




Using the Printhead Loading Modes 

You can use two different printhead loading modes with the 
7421 printer: Mirror Printing mode or Inverse Printing mode. 

If you select Mirror Printing mode, the printer reverses the order 
of the data that is loaded into the printhead. 

If you select Inverse Printing mode, the printer inverts all pixels 
in an image before it sends the data to the printhead. Only use 
Inverse Printing mode to print a small area of a label. 

Note: Intermec does not recommend using Inverse Printing mode for 
printing multiple labels. The printhead is not covered under warranty 
if you use Inverse Printing mode for printing multiple labels.

Communication Problems 



If your printer is not receiving downloaded data, try the 
solutions in this table. 



Symptom 

Printer does not 
communicate 
with the host. 



Possible Causes 

Incorrect 

communications 

parameters. 



Damaged or incorrect 
I/O cable. 



Solution 

Use PrintSet to make sure 
that you have the correct 
communications 
parameters set (such as 
baud rate). 

Check the connections at 
both ends or replace the 
cable. See Appendix B for 
cable information. 



Using Data Line Print Mode 

Use Data Line Print mode to troubleshoot communications 
between the printer and the host, and to test the operation of the 
printer. When the printer is in Data Line Print mode, it prints out 
all downloaded data with the hexadecimal equivalent directly 
underneath it. 

To enter Data Line Print mode 

1. Turn the On/Off switch to the off position. 

2. Press down and hold the Feed/Pause button while turning on 
the printer. 

The hardware configuration test label prints out and the 
firmware program and version number are sent to the host. 
You are now in Data Line Print mode. 

3. Send a few characters down from the host. The printer prints 
out your data with the hexadecimal equivalent directly 
underneath it. 



4-6 



4. Hold the Feed/Pause button down to momentarily suspend 
the test. The printer prints a software configuration test label. 

5. If you press the Feed/Pause button again, the pitch label 
prints. 

To exit Data Line Print mode 

1. Turn the printer power off. 

2. Turn the printer power back on. 

Preventing Data Loss 

Several problems can cause data loss or communications 
problems on the printer. Data loss can result in printing errors or 
missing field data. 

Hardware handshaking involves the use of a hardware wire. 
Software handshaking involves a two-way datalink between the 
devices. The two devices communicate with each other without 
losing data through the use of handshaking. The printer sends 
both forms of handshaking simultaneously when the printer's 
input buffer is full. Any loss of data can cause printing errors or 
missing data. 

Hardware handshaking uses pin 6 or pin 9 of the RS-232 
interface to control data flow. When the printer is using Intermec 
Standard protocol, it holds pins 6 and 9 high when the printer is 
ready to receive data. For help on understanding printer 
protocol, see Appendix B, "Communications Reference." 

The printer holds pins 6 and 9 low when the printer is in one of 
these conditions: 

• Buffer full 

• Ribbon fault 

• No label stock 

• Label at peel-off bar 



4-7 



Your printer uses XON/XOFF protocol for software 
handshaking. When the input buffer is full, the printer transmits 
an XOFF character. This action alerts the host to the fact that the 
printer buffer is full and cannot receive any more data. When the 
printer is ready to receive more data, it sends the XON character. 

To check for communications problems 

1. Check the cabling from the printer to the host system. 

2. Check the interfacing of the devices that are communicating 
with the printer. 

3. Check the printer for proper electrical operation of the I/O 
port. 

4. Test to see that the host system is not overrunning the 
printer's input buffer. 

5. Check to see that the data string being sent to the printer 
contains the correct information. 

Resetting the Printer to Factory Defaults 

Use memory reset if you want to return the printer to its default 
configuration. 

To reset the printer to factory defaults 

1. Turn off the printer. 

2. Lift the printhead and remove all label stock from the paper 
path. 

3. Turn the printer on while holding down the Feed/Pause 
button. 

4. When the print mechanism starts to move, release the 
Feed /Pause button and press it again. The Power light 
should now be flashing red. 

5. Press and hold the Feed/Pause button down for 8 seconds or 
until the Power light stops flashing. The printer resets all 
parameters to their factory default settings.

Communications Reference 



About Communications 



The 7421 printer supports both serial and parallel 
communications. Using the parallel interface with an IEEE 1284 
parallel interface cable (Part No. 590124) provides the best 
performance. 

Your printer has the following hardware and software 
requirements: 

• The host computer must use the American Standard Code for 
Information Exchange (ASCII) for data communications. 

• A serial port or a parallel port must be available on the host if 
you are connecting directly to the printer. 

• The host must support the RS-232 or data communications 
interface. 

For information on configuring the host computer, port 
concentrator, or network controller, see the reference manual for 
the controlling device. 

Serial Communication Protocols 

Communication protocols are important because they determine 
the transmission standards for communications between the 
printer and the host. The printer and the host must use the same 
protocol and parameters to communicate properly. The printer 
supports the flow control and block transfer protocols described 
in the next sections. All of these protocols are point-to-point. 
Application programs and /or ROM BIOS determine which 
protocols your computer can support. For more detailed 
information, refer to the Intermec Data Communications Reference 
Manual (Part No. 044737). 

Intermec Printer Standard Protocol 

Intermec Printer Standard Protocol is a half-duplex protocol. All 
data transmission to the printer consists of status enquiry (ENQ), 
status dump (VT), or message blocks. Each message block starts 
with the Start of Text (STX) characters and ends with the End of 
Text (ETX) characters. Each message block must be 255 
characters or less, including the STX and ETX characters. 



B-3 



The printer returns its highest priority status when it receives a 
valid block (<STX> data <ETX>) or when it receives the status 
request command <ENQ>. When the printer receives the status 
dump command (<VT>), the printer returns all active status. The 
printer status response time ranges from 30 ms to 100 ms 
depending on the complexity of the received message block. In 
the case of a transmission error, the printer responds with a 
<NAK> and discards the entire message block. 

The table below shows printer status conditions in descending 
order of priority: 



Printer Status 


Character 


Buffer already full 


GS 


Ribbon fault 


US 


No label stock 


EM 


Buffer now full 


DC3 


Printhead hot 


SI 


Label at strip pin 


FS 


Skipping 


DC1 


Printing 


DC1 


Ready /Online 


DC1 



Note: Do not confuse the Buffer now full <DC3> status with the 
XON/XOFF characters <DC1> and <DC3>. 

When the printer returns Buffer Now Full (<DC3>) status, it 
accepts the currently received message block. At this time, the 
printer can accept short messages to allow parsing of immediate 
commands such as Reset (<DLE>) or Cancel Batch Printing 
(<EM>). However, if the printer responds with a <GS> to any 
message block, the buffer is already full and the printer discards 
the entire message block. In case of a transmission error, the 
printer discards the whole message block and responds with a 
Negative Acknowledgment (NAK). You should retransmit the 
message block from the host. 



B-4 



XON/XOFF Protocol 

XON/XOFF protocol uses the ASCII characters <DC1> (XON) 
and <DC3> (XOFF) to start and stop the flow of data from the 
host to the printer. The printer does not restrict the message 
length for XON/XOFF protocol. That is, the printer processes 
information as it is being downloaded and stops when there is 
no more information. 

<STX> and <ETX> are optional characters. However, if you send 
an STX, the printer ignores all other characters until you send an 
ETX. 

Intermec provides two versions of the XON/XOFF protocol. The 
Intermec version of XON/XOFF has the printer respond to each 
message with its current status. The other version conforms to 
generally accepted industry standards that include no end-of- 
message response being sent to the host other than XOFF. In 
addition, a DC3 is sent to the host if the printer is offline or if 
media fault occurs. An XON is sent on power up. 

Since the printer uses DC1 and DC3 for data flow control, the 
printer status characters are different from those of the Standard 
Protocol. 



Printer Status 


Character 


Buffer already full 


GS 


Ribbon fault 


US 


No label stock 


EM 


Printhead hot 


SI 


Buffer now full 


DC4 


Label at strip pin 


FS 


Label skipping 


DC2 


Printing 


DC2 


Ready 


DC2 



If the host ignores the printer sending an XOFF, the printer 
resends an XOFF after receiving every 15 characters from the 
host. In the case of transmission error, the printer discards the 
characters with the error and keeps the rest of the message block. 



B-5 



Hardware Protocol 

The printer uses Ready/Busy and DTR (data terminal ready) of 
the RS-232C interface to indicate the printer's status. You can 
configure Ready /Busy and DTR independent of each other and 
independent of the software protocol you select for the serial 
port. You can set each pin to one of these four settings: default, 
high, flow control, and Ready/Busy. 

When you set the pin to high, it stays high as long as the printer 
is powered up. 

When you set the pin to flow control, the pin is high when the 
printer status is ready. The pin is held low when the printer is 
offline or if the buffer is full. 

When you set the pin to Ready /Busy, the pin is high when the 
printer status is ready. The pin is held low when the printer is in 
one of these conditions: 

• Offline 

• Buffer full 

• No label stock 

• Ribbon fault 

• Label at strip pin 

When you set the pin to default, it uses flow control if the serial 
port is set for XON/XOFF protocol. If you are using Intermec 
Standard protocol, the printer uses Ready/Busy. 

User-Defined Protocol 

The printer provides the capability to change protocol characters. 
However, users may not define their own protocol. You can 
substitute characters you want to use as protocol characters, but 
the rules for the chosen protocol do not change. The printer does 
not use any protocol characters that you replace with the NUL 
character. One table of protocol characters exists. You may 
redefine these characters to create a table that all of the protocols 
can use. One possibility for the user to redefine protocol 
characters might be the replacement of control characters with 
printable characters. 



B-6 



Note: Please use caution when replacing control characters with 
printable characters. You cannot replace one control character with 
more than one printable character. 

The following table lists the protocol characters that you can 
redefine and the protocols they affect:

Output: When you use a modem, connect 
to modem DTR pin. 

When using Intermec Standard Protocol, 
this pin indicates that the printer is 
switched on. 

When using XON/XOFF or hardware 
flow control, this pin indicates the printer 
mechanical status and the status of the 
printer input buffer. 

To enable communications, connect to 
signal ground of connected device. 
Completes circuit for all RS-232 signals. 

Input: When you use a modem, connect to 
modem CTS pin. The modem must set 
CTS true before the printer transmits data. 
If not connected, CTS sets itself true. 

Output: When you use a modem, connect 
to modem RTS pin. The modem sets RTS 
to true before transmission. The printer 
sets RTS to false after transmission. 

Output: When not using software flow 
control (XON/XOFF), connect to input of 
connected device (for example, CTS). 
Indicates printer mechanical status and 
status of printer input buffer.

Character Sets 



This chapter contains tables for the character sets that the 7421 
supports. To select a character set, use PrintSet, your 
third-party software application, or the IPL command set. 

International Character Sets 

The following tables show which hex codes to download for 
international characters not available in the U.S. character set. To 
use the tables, find the hex code for the U.S. character that 
corresponds with the character in your language. 

Advanced Character Table 

If you are running your printer in Advanced mode (you are not 
using 86XX Emulation), use this table to find the right hex codes 
for the international character sets.
